Abstract

The invention discloses a method and device for calibrating a rotating shaft and a storage medium. The method includes: specifically, enabling an image acquisition device to acquire a to-be-processedimage containing a first calibration plate; calculating a deflection angle of the position of the image acquisition equipment relative to the position of the first calibration plate; according to thedeflection angle, enabling the rotating shaft to drive the image acquisition equipment to rotate to a first sampling position and a second sampling position respectively; collecting a first sampling image at the first sampling position, collecting a second sampling image at a second sampling position, wherein an included angle formed between the first sampling position and the second sampling position is the maximum rotation range of the image acquisition equipment driven by the rotating shaft to acquire the complete first calibration plate, and calculating attitude calibration parameters of the image acquisition equipment and the rotating shaft according to the first sampling image and the second sampling image. According to the embodiment of the invention, the image acquisition device isdriven by the rotating shaft to acquire images, attitude calibration parameters between the image acquisition device and the rotating shaft are calculated, and accurate calibration of the rotating shaft is realized.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to a method, device and storage medium for calibrating a rotation axis. Background technique [0002] With the continuous development of stereo cameras, depth and color camera information acquisition equipment is widely used in various industries. In the process of image measurement and its visual application, in order to determine the relationship between the three-dimensional geometric position of a point on the surface of a space object and its corresponding point in the image, it is necessary to establish a geometric model of camera imaging, and these geometric model parameters are camera parameters. Limited by the camera's field of view, it can only collect depth and color information in a local direction, so the camera is placed on a motor that can rotate around a fixed axis to achieve 360-degree collection of depth and color information. Under most conditions, th...
